6 squid_cron_selinux - Security Enhanced Linux Policy for the squid_cron
7 processes
8
10 Security-Enhanced Linux secures the squid_cron processes via flexible
11 mandatory access control.
12
13 The squid_cron processes execute with the squid_cron_t SELinux type.
14 You can check if you have these processes running by executing the ps
15 command with the -Z qualifier.
16
17 For example:
18
19 ps -eZ | grep squid_cron_t
20
21
22
24 The squid_cron_t SELinux type can be entered via the squid_cron_exec_t
25 file type.
26
27 The default entrypoint paths for the squid_cron_t domain are the fol‐
28 lowing:
29
30 /usr/sbin/lightparser.pl
31
33 SELinux defines process types (domains) for each process running on the
34 system
35
36 You can see the context of a process using the -Z option to ps
37
38 Policy governs the access confined processes have to files. SELinux
39 squid_cron policy is very flexible allowing users to setup their
40 squid_cron processes in as secure a method as possible.
41
42 The following process types are defined for squid_cron:
43
44 squid_cron_t
45
46 Note: semanage permissive -a squid_cron_t can be used to make the
47 process type squid_cron_t permissive. SELinux does not deny access to
48 permissive process types, but the AVC (SELinux denials) messages are
49 still generated.
50
51
53 SELinux policy is customizable based on least access required.
54 squid_cron policy is extremely flexible and has several booleans that
55 allow you to manipulate the policy and run squid_cron with the tightest
56 access possible.

105 executed with systemd.log_target=kmsg parameter, you must turn on the
106 domain_can_write_kmsg boolean. Disabled by default.
107
108 setsebool -P domain_can_write_kmsg 1
109
110
111
112 If you want to allow all domains to use other domains file descriptors,
113 you must turn on the domain_fd_use boolean. Enabled by default.
114
115 setsebool -P domain_fd_use 1
116
117
118
119 If you want to allow all domains to have the kernel load modules, you
120 must turn on the domain_kernel_load_modules boolean. Disabled by
121 default.
122
123 setsebool -P domain_kernel_load_modules 1
124
125
126
127 If you want to allow all domains to execute in fips_mode, you must turn
128 on the fips_mode boolean. Enabled by default.
129
130 setsebool -P fips_mode 1
131
132
133
134 If you want to enable reading of urandom for all domains, you must turn
135 on the global_ssp boolean. Disabled by default.
136
137 setsebool -P global_ssp 1
138
139

142 The SELinux process type squid_cron_t can manage files labeled with the
143 following file types. The paths listed are the default paths for these
144 file types. Note the processes UID still need to have DAC permissions.

192 SELinux requires files to have an extended attribute to define the file
193 type.
194
195 You can see the context of a file using the -Z option to ls
196
197 Policy governs the access confined processes have to these files.
198 SELinux squid_cron policy is very flexible allowing users to setup
199 their squid_cron processes in as secure a method as possible.
200
201 The following file types are defined for squid_cron:
202
203
204
205 squid_cron_exec_t
206
207 - Set files with the squid_cron_exec_t type, if you want to transition
208 an executable to the squid_cron_t domain.
209
210
211
212 Note: File context can be temporarily modified with the chcon command.
213 If you want to permanently change the file context you need to use the
214 semanage fcontext command. This will modify the SELinux labeling data‐
215 base. You will need to use restorecon to apply the labels.
216
217
219 semanage fcontext can also be used to manipulate default file context
220 mappings.
221
222 semanage permissive can also be used to manipulate whether or not a
223 process type is permissive.
224
225 semanage module can also be used to enable/disable/install/remove pol‐
226 icy modules.
227
228 semanage boolean can also be used to manipulate the booleans
229
230
231 system-config-selinux is a GUI tool available to customize SELinux pol‐
232 icy settings.
